SpaceX almost lands Starship successfully on the third attempt
by Paul Hill
SpaceX has gotten closer to landing Starship SN10 succesfuilly after two failures with SN8 and SN9 in December and January respectively. While the Starship did manage a landing this time, a fire broke out which spread to the propellant leading to a massive explosion destroying the rocket around 8 minutes after landing.
Today’s mission looked uncertain for a while, initially, it was due to take off several hours ago but SpaceX CEO Elon Musk tweeted out to say that the launch was aborted to adjust the thrust limit which he described as “slightly conservative”. After recycling the propellant, the rocket was set for another launch attempt which it carried out successfully.
Today’s mission brings SpaceX one step closer to getting humans to Mars. In the future, Starship with use two stages - the first is a booster stage called Super Heavy and the upper stage is called Starship. Super Heavy will be used to take off from Earth but when taking off from the Moon and Mars, only the upper stage will be needed. During the tests, Starship has been using three Raptor engines but it’s intended that six will be used in the future.
With Starship set to be used for human transportation in a couple of years, it will undergo more testing until the company can get the landing right. It will also have to be trialled using the six Raptor engines at some point and launching atop the Super Heavy booster.
If you missed the test, you can watch it in full above and If you want to know when SpaceX has an upcoming Starship launch, be sure to read This Week in Rocket Launches, a new weekly series posted each weekend detailing all the missions that are planned for the coming week.
Rocket Lab releases plans for reusable Neutron rocket
by Paul Hill
Rocket Lab, one of the many private space firms, has revealed plans for a new reusable rocket called Neutron. The firm said that the 8-ton payload launch vehicle will deploy satellite constellations, go to other planets and take humans into space.
If you’ve been following Neowin’s new This Week in Rocket Launches (TWIRL) series, you’ll know that Rocket Lab’s Electron rocket already delivers satellites into space. While Electron is limited to launching 300 kg satellites, the new rocket will be able to lift 8,000 kg to low-Earth orbit, 2,000 kg to the Moon, and 1,500 kg to Mars and Venus.
Speaking about the announcement, Rocket Lab founder and CEO Peter Beck said:
Much like SpaceX has been doing with its rockets, Neutron’s first of two stages will be designed to land on an ocean platform, this will allow the company to lower costs for customers and get more launches done. Rocket Lab expects to perform Neutron launches from Virginia’s Mid-Atlantic Regional Spaceport at the NASA Wallops Flight Facility. Launching from this facility will eliminate the need for Rocket Lab to build a new pad which will accelerate the time to launch.
The firm said it expects to begin launches of Neutron rockets from 2024 and is looking for sites across America to build a new factory that will support the manufacture of the Neutron rocket and create hundreds of jobs.
NASA unveils Perseverance landing footage and Mars audio
by Paul Hill
Just days after the successful landing of its Perseverance rover, NASA has released extraordinary footage of the landing sequence as well as audio from the surface of the planet where you can make out the sound of the wind blowing. High definition cameras that give a view above and below the rover, as well as the one looking from the vantage point of the sky crane, caught all the action beginning 11 kilometres from the surface to the rover’s landing.
Some of the highlights of the three-and-a-half-minute clip include seeing the Martian surface from a high altitude, seeing the dust on the surface come to life as the rover was close to landing, seeing the sky crane fly off after the rover had touched down and seeing the parachute unfurl. According to NASA, the parachute is also the most massive ever to be sent to another planet.
Commenting on the content, NASA Administrator Steve Jurczyk said:
To watch the descent, check out the embedded video below. To hear the audio from the rover, skip to 40:48 in this NASA event.
Since landing, NASA has been busy checking equipment on the rover to ensure there are no problems. Some of the instruments being checked this week include the Mars Environmental Dynamics Analyzer to look at the weather in the area and the Mastcam-Z which can take panoramic shots of the Jezero crater. The crater used to be a lakebed and contains rocks and sediment which the rover plans to collect up so that it can be examined to find out whether life ever existed on Mars.
Aside from searching for evidence of ancient life, the rover is also carrying the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) which will try to produce oxygen. This part of the mission is key for future human-led missions to Mars where resources will be scarce and the ability to generate oxygen essential.
NASA successfully lands Perseverance rover on Mars
by Paul Hill
The American space agency, NASA, has confirmed that its Perseverance rover has successfully landed on the red planet, Mars. NASA announced the landing from its Jet Propulsion Laboratory in Southern California at 3:55 p.m. EST following a 203-day ride covering 472 million kilometres.
Commenting on the successful landing, NASA Administrator Steve Jurczyk said:
The car-sized rover will do several tests over the next couple of weeks before it begins its mission to investigate rocks and sediment in the Jezero crater, an ancient lakebed and river delta. One of the objectives of the mission, and probably the most exciting, is to search for signs of microbial life that may have once swum in the lake that used to occupy the region - if life is found, it’ll be the first time that we’ve conclusively found evidence of extraterrestrial life.
The samples that Perseverance collects will have to be transported back to Earth for examination with equipment that was too big for the rover to carry, these samples will return with a proposed Mars sample-return mission.
In addition to searching for signs of life, the mission will also carry out the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE), a technology demonstration that will try to manufacture oxygen - this ability will be vital for any human missions to Mars.
The Perseverance rover is planned to operate on Mars for one Martian year or 687 Earth days. Despite the mission only being funded for around two years, the rover itself will likely last many more years if it has the same luck as the Curiosity rover which landed in 2012 and is still operational.
UKSA and Rolls-Royce to study nuclear-powered space travel
by Paul Hill
The UK Space Agency (UKSA) and Rolls-Royce have signed a research contract that will bring the two together to investigate nuclear energy as a source for deeper space exploration. UKSA said that nuclear is a plentiful source of energy that could propel spacecraft at huge speeds which could “revolutionise” space travel.
In terms of results, nuclear propulsion is expected to be twice as efficient as chemical engines which are in use today and a trip to Mars could be cut in half and take just three to four months. According to the government, the new agreement will also generate skilled employment across the country.
Commenting on the partnership, UKSA Chief Executive Dr Graham Turnock said:
Aside from faster travel, nuclear propulsion would help cut astronauts’ dosage of radiation that they get hit with when in space. UKSA said that the longer you spend in space, the greater the amount of radiation that you’re exposed to so faster journeys would mean less radiation exposure.
In the outer Solar System, the sunlight is too dim to power solar panels and fuel cells are not a reliable store of energy according to UKSA. Using nuclear power, therefore, would help to enable more missions in the outer Solar System.
