Uh-oh....

1552 GMT (10:52 a.m. EST)

A red team is being prepared to enter the launch pad to investigate the liquid oxygen leak. The launch team has paused pressurization of the gaseous nitrogen system, and officials are donning proper safety gear to enter the pad.

1608 GMT (11:08 a.m. EST)
The red team took a look at the small liquid oxygen leak on a ground maintenance line and found it was not dripping onto any important launch pad systems. The issue has been cleared and launch remains on schedule for 1:07 p.m. EST (1807 GMT).

The countdown was paused for about 3 minutes a few minutes ago as the launch team worked to resolve the issue. The time will be made up in a build-in hold in a few minutes.

That was certainly a nice and clean launch + climb to orbit. Job well done by Orbital!

Orbital Sciences is proposing enlarged versions of Cygnus, both for CRS round 2 and as a beyond Earth orbit (BEO) habitat for use with NASA's Orion exploration vehicle.

Guess we now know who will supply the non-Russian, non-Ukrainian Antares first stage.

ATK made the solid fuel SRB boosters for the Shuttle, and will do the same for NASA's Space Launch System.

ATK also proposed using a stretched SRB booster as the first stage of a manned launcher named Liberty, but it lost out in the second round of the NASA Commercial Crew program.

Orbital Sciences, ATK Announce "Merger of Equals"

PARIS — Satellite and rocket builder Orbital Sciences and rocket-motor builder ATK on April 29 said they have agreed to merge their aerospace and defense divisions in a $5 billion transaction that has been definitively approved by both companies.

The new company, to be called Orbital ATK, will count 13,000 employees and in 2013 would have generated $4.5 billion in revenue.

The companies said ATK would be spinning off its commercial sporting-equipment group to ATK shareholders.

The companies described the deal as a "merger-of-equals combination." ATK shareholders will have 53.8 percent the new company, with Orbital investors owning 46.2 percent.

A note about coming changes to Antares

The first stage tanks, plumbing and wiring are made Yuzhnoye SDO in Ukraine, and the engines are US modified NK-33's made by the Kuznetsov Design Bureau in Russia. Orbital had planned to upgrade Antares with larger tanks and the more powerful Russian made RD-180 engine.

Needless to say all of these present a problem what with the current international situation.

Because of the merger between Orbital Sciences and ATK, makers of the Shuttle and SLS solid boosters, there have been strong hints Orbital will shift gears and use a new, larger, solid fuel first stage. It's also possible this first stage will be segmented, allowing Orbital to adjust the burn time by adding full or partial segments in future upgrades.

This would certainly eliminate the 'Russia problem' and guarantee their supply chain would be uninterrupted.
