A lunar free return mission like Apollo 8 isn't that hard - quite possibly do-able with the in development reusable Falcon 9 (the Grasshopper project) and Dragon fitted with a service module instead of the trunk. With reuse the cost drops precipitously from the 10,000+ / lb for the shuttle flights to $100 / lb or less.

A rocket engine and spaceflight development company could locate its headquarters near Midland International Airport after votes on Monday by the Midland Development Corp. and the Midland City Council.

According to agendas posted Thursday, the two entities will vote on an incentive deal with XCOR Aerospace Inc., which currently operates from Mojave, Calif.

The company is being offered an incentive deal of about $10 million to create a corporate headquarters in Midland that eventually would include enough employees to necessitate a $12 million payroll, said Robert Rendall, MDC board secretary, who?s been working on the project.

?I didn?t realize this industry is as mature as it is,? Rendall said.

?I?m excited we?ve got the opportunity to kind of get in on the ground floor.?

Rendall said the MDC was connected to XCOR through ROI, a consulting firm that provides the MDC with leads, among other things.

Andrew Nelson, chief operating officer for XCOR, said Midland had been on its radar so when executives received a call from the MDC they were interested in learning more. Between the weather, the open space around Midland International Airport and the business climate, Nelson said Midland is an ideal place for them.

?Midland and Texas were high on that list as a business-friendly community and business-friendly state,? he said.

If the deal is approved Monday, XCOR will operate a research and development facility in Midland and will conduct flight tests here.

As part of the incentive package, XCOR is being offered $2 million for creating its headquarters in the Tall City, $3 million toward lease payments and capital improvements at the existing hangar and $5 million for performance incentives, according to a draft contract provided to the Reporter-Telegram.

XCOR would have to meet payroll requirements that would increase each year. After five years, the company would have to certify to the MDC that its Midland payroll is at least $12 million.

City council members and MDC board members said they?re ecstatic about the deal.

?Diversification is in progress,? said Jerry Morales, councilman at large. ?That was the main purpose for the creation of the MDC.?

Other officials said in addition to immediate diversification, they?re hopeful XCOR?s relocating to Midland will serve as a catalyst to bring other aerospace companies to the area.

?This is a great company and we?re looking forward to having them locate their operation in Midland,? said Scott Dufford, councilman at large.

Commercial Space Company XCOR Announces R&D Headquarters in Texas

Gov. Rick Perry joined XCOR Aerospace and the Midland Development Corp. to announce the creation of XCOR's new Commercial Space Research and Development Center headquarters at the Midland International Airport. XCOR develops and produces reusable launch vehicles, rocket engines and rocket propulsion systems, and will create 100 jobs at this new facility.

"This is a great day for Midland and a huge step forward for the State of Texas. Visionary companies, like XCOR, continue to choose Texas because they know that innovation is fueled by freedom," Gov. Perry said. "Whether on the cutting edge of biotech, communications, commerce or privatized efforts to serve the needs of the next generation of space explorers, you can find Texas at the forefront of the movement."

XCOR's new headquarters will focus on development of the Lynx, the company's next generation reusable launch vehicle. Lynx is a two-seat suborbital vehicle that takes off and lands like normal aircraft. The vehicle will carry a pilot and one spaceflight passenger, and will provide affordable launch services for academic, scientific and engineering markets.

"We are pleased to be establishing our R&D Center in Midland, Texas, where the weather, surrounding landscape, the airport, and the local & state government environment are ideally situated for the future growth and the ultimate realization of a fully reusable orbital system," Andrew Nelson, chief operating officer of XCOR Aerospace, said. "With future suborbital operational sites on the East and West Coasts of the United States and around the world, plus a manufacturing and test facility geographically separate from our R&D facility, Midland will truly be at the heart of XCOR's innovation engine."

"We are elated to welcome XCOR to Midland and to the state of Texas. The Permian Basin is a proud and industrious area where we have developed and maintained the leadership, infrastructure and highly capable work force that will support the further development of XCOR systems," Rep. Tom Craddick said. "With the announcement of the new XCOR research and development headquarters being built in here, Midland will soon be known world-wide not just as a leader in oil and gas industry, but also as a trailblazer in the aerospace industry."

"The decision to establish XCOR's R&D Center Headquarters in Midland came after intense competition from other locations," Midland Development Corp. Executive Director Pam Welch said. "Once the technical and operational needs of XCOR were met, the final factors influencing the decision to locate R&D to Midland included the friendly business climate, a predictable regulatory environment and the State of Texas tort reform initiatives. These factors allowed XCOR to see a long term future happening in Midland."

XCOR Announces ATK as Lynx Mark I Wing Detailed Design And Build Contractor

XCOR Aerospace has issued the initial phase of a two-phase contract to ATK's Aerospace Structures Division [NYSE:ATK] for the detailed design and manufacture of the Lynx Mark I suborbital reusable launch vehicle (RLV) wings and control surfaces. This announcement represents a critical milestone in the march toward assembly, test and entry into commercial service of the Lynx.

"This partnership with XCOR will provide unique insights and innovations," said Andrew Jackson, vice president of ATK's Aerospace Structures Division Launch Segment.

"ATK is honored to continue our heritage in creating composite manufacturing solutions for spaceflight and excited to engage in this commercial environment with XCOR."

"As an established industry leader it is only natural that XCOR sought to work with ATK as a key collaborator in the development of Lynx wings," said XCOR Chief Executive Officer Jeff Greason.

"Our engagements with ATK impressed me from the start, not only due to their position as a leader in the industry, but through their immediate grasp of the unique challenges we face in the construction of Lynx wings. The story of Lynx is the story of sound design and reliable engineering. We could not be more thrilled to work with ATK."

XCOR Chief Operating Officer Andrew Nelson added that "until recently NewSpace companies and established aerospace primes like ATK often had minimal interaction with companies like XCOR as the subcontractor.

With this effort we are establishing a model of how smaller NewSpace companies may utilize established government primes as our suppliers; ATK has demonstrated they are nimble, cost effective and can leverage deep experience from prior larger projects."

The initial wing and control surface design has been developed by XCOR to rigorous design standards to enable the craft to perform tens of thousands of flights to and from suborbital altitudes exceeding 100 kilometers.

ATK will create a detailed design ready for manufacture, working with structural and flutter analysis experts from Quartus Engineering in San Diego, Ca.

The wings will be installed on the Lynx Mark I, which is the prototype of the Lynx family of suborbital RLVs from XCOR; the production models are called Lynx Mark II.

http://www.parabolicarc.com/2013/03/20/silicon-valley-space-center-to-develop-suborbital-payloads-for-lynx/

The Silicon Valley Space Center will develop four scientific payloads to fly on the XCOR Lynx spacecraft, which is currently under construction in Mojave, California.

?The Silicon Valley Space Center is proud to support the Citizens in Space program,? said Dr. Sean Casey, co-founder of the Silicon Valley Space Center. ?This is a unique opportunity to leverage the technical expertise of the Silicon Valley community in support of citizen science and the emerging suborbital spaceflight industry.?

Citizens in Space has acquired an initial contract for 10 flights on the XCOR Lynx. This initial flight campaign will carry 100 citizen-science payloads and 10 citizen astronauts who will act as payload operators.

The experiments being developed by the Silicon Valley Space Center will serve as pathfinders for those citizen-science experiments. ?When a developer is learning a new programming language or technology, he starts out by building a ?Hello, world? application,? Casey said. ?These payloads serve as ?Hello, world? apps for space. They will provide a starting point for citizen scientists who are just getting started in space science.?

The Silicon Valley Space Center is currently reviewing candidate experiments in microgravity materials processing, fluid physics, life sciences, and other fields. Experiments built by the Silicon Valley Space Center will be featured at a series of ?Space Hacker? workshops for citizen scientists, the first of which is scheduled for May 4-5 at the Hacker Dojo in Mountain View, California.

?We are pleased to welcome the Silicon Valley Space Center as a partner,? said Edward Wright, project manager for Citizens in Space. ?The Center brings the scientific experience and knowledge of the Silicon Valley culture needed to make this program a success.?

?Payload designs will use open-source hardware wherever possible,? Casey said. To achieve this goal, the Silicon Valley Space Center is teaming up with Infinity Aerospace, a Silicon Valley startup that offers Nanorack-compliant and certified technologies for research experiments and commercial activities aboard suborbital and orbital facilities. ArduLab, an Arduino-based microgravity platform developed by Infinity Aerospace, will serve as the underlying hardware for experiments developed by the Silicon Valley Space Center.

Lynx Cub Payload Carrier Being Developed at Texas A&M

College Station, Texas (Mar. 28, 2013) ? A new payload carrier promises to dramatically reduce the cost of access to space for small scientific and education payloads.

The Lynx Cub Payload Carrier was announced today by the United States Rocket Academy. The Lynx Cub Carrier will fly on the XCOR Lynx space plane, now under construction at the Mojave Air and Space Port, and carry up to 12 experiments on each flight.

?The Lynx Cub Payload Carrier is a versatile system that installs in the Lynx cabin, behind the pilot?s seat, allowing small experiments to be carried as secondary payloads on any Lynx flight,? said United States Rocket Academy chairman Edward Wright. ?The Cub Carrier can be installed and removed quickly for frequent, low-cost flight opportunities.?

Citizens in Space, a project of the United States Rocket Academy, will fly the Lynx Cub Carrier on 10 Lynx missions beginning in late 2014 or early 2015. The Lynx Cub Carrier will also be made available to other XCOR customers, as ready-to-fly hardware or as an open-source hardware design.

?XCOR Aerospace is pleased to welcome the new Cub Carrier to the Lynx family,? said Khaki Rodway, XCOR Director of Payload Sales and Pperations. ?The Lynx Cub Carrier is an ideal platform for small materials-processing, fluid-physics, life-science, and engineering experiments. University teaching and research, K-12 education, citizen science, government and industrial R&D will all benefit from the convenient simple interfaces, rapid integration, and affordability of Lynx Cub experiments.?

The Lynx Cub Carrier is being developed by the United States Rocket Academy and the Space Engineering Research Center, part of the Texas A&M Engineering Experiment Station (TEES), with support from XCOR Aerospace. Design and fabrication are being done by Texas A&M faculty and students and TEES researchers.

?Lynx Cub payloads are based on the popular 1U, 2U, and 3U CubeSat form factors, which are de facto international standards for small scientific payloads,? said Chip Hill, Director of the Space Engineering Research Center. ?The payload carrier provides physical accommodations, electrical power, and limited thermal control for Lynx Cub experiments.?

The Lynx Cub Carrier will be flight-ready in September 2013 and will be included in the XCOR Lynx flight test program.

?For the test flights, we will load the Lynx Cub Carrier with payload simulators, accelerometers, gyroscopes, and environmental sensors,? Wright said. ?While XCOR is proving out the vehicle, we?ll be gathering baseline data on the thermal environment, the acoustical environment, acceleration, vibration, etc. ? data that will help guide experimenters in their payload design.?

?The Space Engineering Research Center has put together a first-class team for this development program,? Hill said. ?The involvement of Texas A&M industrial and systems engineering students as key team members, under the mentorship of Dr. Justin Yates and direction of technical lead Dr. Frank Little, provides an excellent opportunity for students to gain hands-on experience with real space hardware.?

A&M student Cress Netherland said, ?Developing the Lynx Cub Carrier presents a challenging and unique problem. We are extremely excited about the opportunity to apply our studies to a real world application.?

The Space Engineering Research Center, part of the Texas A&M Engineering Experiment Station in College Station, is also a member of XCOR?s global network of payload integrators, which provides value-added services for Lynx payload developers. TEES is an engineering research agency of the State of Texas and a member of The Texas A&M University System.

XCOR Aerospace, which is developing the suborbital, fully reusable Lynx spacecraft for a variety of scientific and commercial missions, is currently headquartered in Mojave, California. The company will relocate its headquarters to Midland, Texas later this year.

The United States Rocket Academy, a non-profit educational organization that studies and promotes the scientific, military, and commercial applications of human spaceflight, is also located in Texas. Citizens in Space is the United States Rocket Academy?s flagship program.

This weeks SpaceVidCast net space show has a few short stories the an interview with XCOR's COO.

Lynx I (dev platform) to fly this year. Lynx III with the sat launcher in 2-3 yrs flying from the US East coast, probably KSC. Lynx-like orbital system being worked on.

Hiring :) Looking for people that know Solid Works and build things - even if it's race cars (since they're making piston pumps for rockets.)

They claim their piston cryo fuel/oxidizer pump will work thousands of hours vs just minutes for turbopumps, and will be cheaper.

Press Release

CFIUS Approval Clears XCOR Aerospace?s First Close of Series B Financing

XCOR Raises $14.2 Million of Investment Capital Led by Dutch Investors

27 May 2014, Mojave, CA ? XCOR Aerospace announced today that the United States Treasury Department?s Committee on Foreign Investment in the US (CFIUS) has approved the Series B lead investment by Dutch investors. The first closing of XCOR?s new round of finance issued $14.2 million of Series B preferred shares. XCOR will use the funds to bring the XCOR? Lynx? suborbital spaceplane to market.

The Series B financing was led by Space Expedition Corporation (SXC) of The Netherlands. Michiel Mol and Mark Hoogendoorn of SXC will join the current five members on the XCOR Board of Directors. The first round also included many existing and new investors including: board member Esther Dyson, Pete Ricketts (co-owner of the Chicago Cubs), and a number of Silicon Valley entrepreneurs and early-stage investors. A smaller second closing is scheduled over the summer.

The SXC investment in XCOR signals a strong commitment to the commercial space industry by the Dutch entity, which is also XCOR?s lead wet-lease customer and general sales agent.  Michiel Mol said, ?With this investment in XCOR, we?re closing ranks with our most strategic partner. We will take the next step together toward our first commercial spaceflight. I?m proud to become a part of this fantastically dedicated team of ?future makers? and game changers.?

Mark Hoogendoorn noted, ?Investing in XCOR is much more than investing in innovative technology and a team of highly skilled engineers. Most of all, it?s investing in a long term vision we strongly believe in that will enable a new era of sustainable and regular space access that will positively impact all mankind.?  

Jeff Greason, Founder and CEO of XCOR, said, "We are very pleased to have this first closing of the Series B and welcome Michiel and Mark to the Board. This investment will allow us to accelerate and run in parallel several final developments in the critical path to first flight."

"This first closing of the Series B is a signal to the market that XCOR is moving ahead with its plans for commercial service and that we are nearer to that goal," said Andrew Nelson, Chief Operating Officer of XCOR.  ?The Series B will remain open for a limited time as we complete discussions with a few more potential investors.?

Although SXC acquired a minority position without control provisions in XCOR, the company took the cautious route of submitting the investment to CFIUS for review prior to an official public announcement.  CFIUS agreed that no control provisions exist and that the investment is not a so-called ?covered transaction.?

XCOR DEVELOPS LYNX SIMULATOR IN PARTNERSHIP WITH PROTOBOX LLC AND AIR FORCE RESEARCH LAB

November 16, Mojave, California  XCOR Aerospace announced today that it has completed work on its Lynx simulator system, built by Protobox LLC in conjunction with the Air Force Research Lab (AFRL) at Wright Patterson Air Force Base in Dayton, Ohio.

This simulator will provide XCOR invaluable training as the test pilot team prepares for Lynx flight test.

Dedicated aerodynamic modeling of the vehicle in the LAMARS (Large Amplitude Multi-Mode Aerospace Research Simulator) at AFRL (Air Force Research Laboratory) in Dayton, Ohio has provided XCOR with valuable insight into Lynx spacecraft performance and handling qualities. said XCOR Chief Executive Officer Jay Gibson. As a result, we contracted with Protobox to provide an in-house version of the simulator at XCORs Hangar 61, in Mojave, California.

AFRL-developed modeling and simulation software, including a Government Open Source Image Generation (IG) software package known as SubrScene, was integrated into a mockup Lynx cabin and nose at Hangar 61. Protobox provided integrated flight and engine controls, along with a representative pilots instrument panel. Four 80, high-resolution LCD screens that mimic the pilots expected field of view throughout the mission profile provide a 180 degree field of view. A control station behind the simulator can create many different flight scenarios. It also has the ability to alter a variety of vehicle performance parameters that will help train the crew in hypothetical emergency situations.

Besides validating the simulation model of the Lynx vehicle, writing operational procedures and performing flight test rehearsals, our pilots are giving feedback on the pilot vehicle interface (PVI) during their flights in the simulator. Through this, engineers can optimize the interface design based on true pilot insight and simulation experience.

The sim is a great asset and has awesome graphics, remarked XCOR Experimental Test Pilot Harry Van Hulten. I thought I was flying an F-16 test mission in the skies over Mojave and Edwards AFB again. This will significantly accelerate development of modelling and simulation and operational procedures.

15-10-23_erik-brian-simulator-7758.jpg

XCORs Experimental Test pilot Harry Van Hulten in the Simulator

The simulator was made possible through a Cooperative Research and Development Agreement (CRADA) that allowed XCOR test pilots and engineers to utilize AFRLs unique simulator. The LAMARS is maintained and operated by the Aerospace Vehicles Technology Assessment & Simulation (AVTAS) Branch of AFRL. The day-to-day maintenance and operation of the LAMARS simulator is supported by Protobox LLC, which then built XCORs in-house version.

We look forward to further collaboration with AFRL, AVTAS and Protobox. This is just the beginning, Gibson noted.

This is a spacecraft, not a WW-2 bomber. It has to re-enter from 68+ miles up at high supersonic velocities, so the glass has to have thermal protection capabilities - usually fused quartz. X-15 had flat fused quartz glass. So did SR-71. Shuttle? Yup. And others. 

The Lynx presure vessel windshield is curved polymer, which would melt during re-entry, but the thermal glass layer outside of it (with an insulating space) is in flat panels because that's far cheaper than curved thermal glass and it can take the heat. The cost difference is in the 6 figures.

That money is better spent elsewhere.

XCOR appears to have found a "niche altitude" near/at the Karman Line (100 km). This would obviously be a prototype for a much larger unit in the future, as this size will not support itself in general revenue from a passenger and a few cube sats/ camera ride, since NewSpace is constantly driving prices down. Hope they have success in this venture...would be a great view up there and no shortage of paying customers.

I do have reservations of such a large surface area exposed to re-entry, particularly the control surfaces, but then, they are more than aware of this.

Space roadster.....:woot:

I just can't take a plane that looks like a Lada car and with more panel lines on the cockpit windows than a early WWII bomber seriously. 

Noooooooo! Not the RIVA! Anything but *that*!!

There's gotta be a law somewhere ... :D

XCOR claims major breakthrough with its engine technology

 

xr-5k18-rocket-engines-lynx-configuratio

The XR-5K18 Engines in Lynx configuration.

 

Quote

XCOR Director of Engineering and acting CTO Michael Valant announced that his team has reached an important milestone in the development of the reusable 5K18 Lynx main propulsion rocket engine. His engineers were able to 'close the loop' of the thermodynamic system under test conditions, a key technology for the Lynx sub-orbital vehicle.

 

This technology includes a novel method to drive essential engine parts using waste heat from the rocket engine, thus eliminating the need for adding large, heavy compressed gas tanks to the vehicle.

 

This propulsion system is an essential part of the Lynx "instant reusability" because it allows the vehicle to be flown multiple times per day without costly servicing of components. In addition, XCOR engine technology could be used to benefit other rocket-propelled vehicles in the same way.

 

Valant: "There's still some work to do to improve the cycle efficiency before this engine, that in its basic 'open cycle' form has already had hundreds of successful test firings, is ready for flight, but this is a massive step forward for us in the development of this truly groundbreaking technology.

 

"I'm genuinely proud of my teams for working so painstakingly to reach this goal."

 

Michael Valant, newly appointed acting CTO, has currently 20 years of experience in rocket propulsion system design and development. Since 2006, he has worked at XCOR to design and develop various propellant systems and components, to include rocket engines, valves and pumps for kerosene and liquid oxygen to fit the design requirements for the XCOR Lynx sub-orbital vehicle main propulsion system.

Not Lynx, but a huge deal

 

XCOR AND ULA AWARDED US AIR FORCE PROPULSION CONTRACT

 

Midland TX, March 9, 2016, United Launch Alliance (ULA), the nation's premier launch services provider, has awarded XCOR Aerospace with a new contract through the United States Air Force to develop an upper stage propulsion system for Vulcan, ULA's next-generation launch system.

 

Jay Gibson, President XCOR: "We are very proud of our long and ongoing relationship with ULA, and very pleased ULA has chosen XCOR as a potential upper stage engine provider. We have already begun work on the 8H21 development, and are very excited about the long term potential for XCOR to support ULA and the United States Air Force in their evolving launch efforts."

 

XCOR's 8H21 LO2/LH2 engine (25k lbf thrust) is being developed for the upper stage propulsion for ULA's Advanced Cryogenic Evolved Stage (ACES). Since 2008 XCOR has been working closely with ULA on a subscale 2,500 lbf thrust liquid hydrogen engine, which was successfully built and tested in 2015.

 

In 2016, XCOR began development on the full scale 25k lbf thrust liquid hydrogen engine, the 8H21, under a privately funded contract with ULA. This partnership with the Air Force will further support this engine development.

The 8H21 is a liquid oxygen, liquid hydrogen rocket engine that uses XCOR's proprietary piston pumps and other unique rocket engine components to deliver a low cost solution for easier access to space. The 8H21 also uses the same technology that XCOR has been developing for their own reusable engine programs, designed with forward capabilities in mind for future reusable engine development programs.

    • Why Delta Chat is the best decentralized messenger you have probably never tried by Paul Hill There is no shortage of messaging apps out there; we have WhatsApp, Messenger, and Telegram, just to name a few. While Meta has taken steps to incorporate encryption into Messenger and WhatsApp, they still leave a lot to be desired. If you are in the market for a messaging app that promotes security, privacy, and optional anonymity, you'll want to read what I have to say about Delta Chat. For those not familiar with Delta Chat, rather than relying on centralized servers as you do with Facebook Messenger, it relies on email. Essentially, it is a chat interface that feels like a messaging app, but secretly in the background, it is firing off emails. In the past, you used to have to sign in with your email account. When you sent messages to people, it would just be sending encrypted messages to their inbox, which their Delta Chat client would decrypt. When I first learned about Delta Chat, it required users to sign in with an email account, but I was pleasantly surprised upon trying it in 2026 that this is no longer a requirement, or the preferred method was to use the app. Recently, I’ve tried UAD-ng on my old Nokia 3.4 to disable most of the Google apps because the bootloader is locked, and this is the next best option. While finding replacement apps in F-Droid, I came across Delta Chat again, and it has undergone quite a big change since I last used it, with its new chatmail relays, which no longer require you to sign in to your own email account, providing anonymity, and they offer greater security. Android and Desktop Delta Chat apps. Not only does it run on my de-googled phone, but it also works on desktop computers and iOS, making it truly ubiquitous. For me, Delta Chat is a wonderful alternative messenger because it gives you more control. It supports switching between different profiles, which you can set up super quickly; you don’t register a username, you don’t register a password. The only thing you do have is a random string email address on a chatmail relay (which you don’t have to memorize). To maintain access to your profile, you just need to add a second device to your account via QR code or make a backup of your account, which you can restore later. Fail to do these, your account is gone - as it should be if you don’t want to leave accounts that could get hacked later on. My decision to block Google stuff on my Nokia was done for practical reasons; the device sucked when it launched, and it sucks even more now. The nice thing about F-Droid and the apps within is that they’re usually lightweight, free of bloat, and work well on that device. What was inconvenient for me was that it was hard to send messages from that device, say if I wanted to copy a code over to my main phone or send family members a link from that device. That’s when I decided to look at the available chat apps and saw Delta Chat. Another nice thing about Delta Chat is its notifications. Some messaging apps rely on Google’s ecosystem for notification transport on Android; however, with Delta Chat, it can use Google’s solutions if you have Play Services or MicroG installed. Otherwise, it is able to keep a background connection to the chatmail relay server so that you can get notified when you receive a message. As free software, the code of Delta Chat is open for all who want to take it and build upon it. In the future, if the developers of Delta Chat make a catastrophically bad decision and take the app in an undesirable direction, users can take the code and fork the project. This contrasts with closed-source apps from corporations that can take their products in any direction they like. By relying on free software instead of closed-source programs, you actually control your computing. I’ve spoken at length about how running this type of software is like owning your own home rather than renting it. The same applies here; if you use Delta Chat, you don’t need to worry about it going away in the future. Whether it is Telegram, WhatsApp, or Messenger, you are required to register a username and password to use these services. A major flaw in this design is that anyone can try various passwords and potentially break into your account with your complete chat history intact. Sure, there is encryption in Messenger, where you need a second PIN and two-factor authentication in Telegram, but breaches happen all the time. Unlike before, when you used to sign in to your email account to send and receive messages, the primary way to do it now is to create an account on a chatmail relay. The resulting email address is a random string followed by the name of the relay you pick. This means you can start and begin adding contacts Without a username and password, you either need to ensure you have a backup or at least one device running your Delta Chat profile. The primary way to log in on another device is to go to the settings and add a second device. Then, you’ll just scan a QR code with your new device, and it’ll log in to your account and sync all your chat history and contacts. To end users, Delta Chat just looks like any instant messenger; however, it is really sending your messages as encrypted emails to your contact. This is pretty cool from a censorship perspective, as it makes the service more difficult to block. Previously, the main way to use the app was by logging in with email, but nowadays, it’s recommended that you use chatmail relays. Chatmail relays temporarily hold messages in case your device is offline. They are cheap, simple servers that don’t store data as group states. Other information, like your name and avatar, only exists on your device and the devices of those you share your contact information with. The relays are also decentralized and operated by various groups and individuals. It is even possible to set up your own chatmail relay, but most people will want to use one hosted elsewhere. To keep your messages secure, Delta Chat uses a secure subset of the OpenPGP standard that gives you automatic end-to-end encryption. It also uses Secure-Join to exchange encryption setup information through QR-code scanning or invite links. Autocrypt is also used to automatically establish end-to-end encryption between contacts and all members of group chat, but sometime this year Autocrypt v2 will be rolled out, bringing post-quantum resistant encryption and forward secrecy. The Delta Chat FAQ is an interesting read that explains many more details about the app. Credit: Pexels Delta Chat is unique among messaging apps because it is built on email, a technology that’s decades old and isn’t going anywhere soon. What’s more is that email is not centralized either, so it’s far more difficult for any authoritarian regime to disrupt the Delta Chat app. I haven’t spoken too much about features yet, so I will do that now. Delta Chat allows you to do one-on-one chats, group chats, and create channels. It also supports file sharing and making audio and video calls when chatting one-to-one, but it’s not available for group chats right now. At the time of writing, the calling functionality is disabled and can be enabled in Settings > Advanced > Debug Calls. I have used the video calling feature, and the quality is excellent. It works over WebRTC, another open standard. The app also lets you send voice notes, enables disappearing messages, and has its own app ecosystem. I did try playing chess one time there, but it was a bit spotty; though, we did manage to complete the game with a victory for me. To add people to Delta Chat, you can either give them your Delta Chat link or your QR code to scan. These are the only ways to add users, so you won't have any spam bots bothering you. If the people you want to chat with don't have the app yet, just send them your link, and it will take them to a webpage where they can install the app and then add you. It's really quick for them to install it and get started, which is nice. Credit: Microsoft. The Majorana 2 quantum chip unveiled in 2026. I do not think quantum computers are too far out now, and I do hope that Delta Chat is able to push out Autocrypt v2 sooner, rather than later, so bad actors do not attempt to collect encrypted communications and then decrypt them in the future using quantum computers. By getting people’s messages post-quantum-safe now, users won’t have to worry when quantum computers start cracking legacy encryption. Overall, I would recommend this app to people who are already past WhatsApp and Messenger and have perhaps begun using apps like Telegram or Session. It shares a lot of characteristics with these apps and goes a lot further than Telegram in terms of security. By being based on email, it is also resistant to censorship, and the lack of a username and password makes you anonymous (if you want to be) and safe from brute force password cracking attempts. Let me know in the comments if you’ve tried Delta Chat recently. Do you think it's a good bulwark against governments that are tightening their grip on the internet?
