- The Ariane 5 launch of two communications satellites was aborted Wednesday after the rocket’s main engine ignited. According to Arianespace, the rocket’s Vulcain main engine ignited as scheduled at 2:45 PM Phoenix time (2145 UTC) Wednesday, but the checkout process during ignition detected an unspecified anomaly, shutting down the engine before the two solid-rocket boosters ignited.

- Amateur sleuths have tracked down the X-37B on its second secret mission. And the information the skywatchers are finding says quite a bit about the classified operations of this mysterious spacecraft.
- NASA’s Dawn spacecraft is preparing to orbit the “asteroid” Vesta. This intriguing world, scientists now know how special this world is, has been the subject of some debate on how to classify it. “I don’t think Vesta should be called an asteroid,” said Tom McCord, a Dawn co-investigator based at the Bear Fight Institute, Winthrop, Wash. “Not only is Vesta so much larger, but it’s an evolved object, unlike most things we call asteroids.”
- A 165-foot-tall Ariane 5 rocket is scheduled to lift off at 2145 UTC Wednesday from the ELA-3 launch zone at the Guiana Space Center, a French-run spaceport in Kourou, French Guiana. It will be carrying communications satellites for the Middle East and Africa

- NASA has unveiled a new facility to help ready commercial rockets for launch, and the first work at the new site should begin this month in preparation for a test flight to the International Space Station later this year. The facility is six stories tall, about 250 feet (76 meters) long and 150 feet (49 m) wide. Medium-class rockets with multiple stages will be assembled at the HIF, then rolled out for launch at a nearby Wallops pad. NASA’s first customer for the new rocket facility is Virginia-based Orbital Sciences, which will use the new building to assemble its Taurus 2 rocket.
- On Thursday, March 24 at about 4:00 PM Phoenix time (2300 UTC), NASA’s Stardust spacecraft will perform a final burn with its main engines. This will be a burn to depletion, and will answer the question about how much fuel Stardust had left in its tank. “We’ll take those data and compare them to what our estimates told us was left,” said Allan Cheuvront, Lockheed Martin Space Systems program manager for Stardust-NExT. “That will give us a better idea how valid our fuel consumption models are and make our predictions even more accurate for future missions.”

The trio landed at 12:54 AM Wednesday at a site northeast of the town of Arkalyk.
- The launch of a Soyuz spacecraft carrying the next crew for the ISS has been delayed several days because of a technical issue, Russian officials said Monday. The Soyuz TMA-21 spacecraft was scheduled for launch March 30 from the Baikonur Cosmodrome, but has now been pushed back to early April. Russian officials said that a problem with the spacecraft’s communication system, caused by a faulty capacitor, caused the delay. The Soyuz will ferry to the ISS Russian cosmonauts Andrey Borisenko and Alexander Samokutyaev and NASA astronaut Ron Garan. The delay will not affect the return to Earth of three current ISS crewmembers, Scott Kelly, Oleg Skripochka, and Alexander Kaleri, who are scheduled to undock from the ISS Tuesday night on the Soyuz TMA-01M and land in Kazakhstan.
- SpaceX will launch a communications satellite for SES, the first launch deal the entrepreneurial launch company has won from a major satellite operator. SpaceX will launch the SES-8 satellite for SES in the first quarter of 2013 on a Falcon 9 from Cape Canaveral, the companies announced Monday. SES-8 is a medium-sized communications satellite being built by Orbital Sciences and will operate from 95 degrees east. The contract is the first time one of the big four satellite operators (Eutelsat, Intelsat, SES, Telesat) has purchased a launch from SpaceX, a signal that traditionally risk-averse customers like major satellite operators have become comfortable with the Falcon 9, which launched successfully twice last year. Falcon 9 prices start at around $50 million, significantly less than other commercial launchers with similar capacities.

- Political wrangling may end up killing both manned and unmanned space exploration. With the emphasis on budget cuts, the robotic exploration program is being squeezed and two prominent probes to Mars and Europa will probably die. Although the Augustine Commission condemned the Ares V rocket (Constellation Program) as unaffordable to operate even if we could afford to build it, Congress has now mandated that NASA build and launch a similar vehicle by 2016. We are doomed.
