The US has lacked any manned space flight capabilities since the Shuttle was retired back in 2011, but the goal has been to get commercial launch operations up and running to fill in the gap. However, that process has been much slower than originally envisioned. According to a new report from the Government Accountability Office (GAO), neither SpaceX nor Boeing are likely to conduct a manned launch in 2019.
The US government started the Commercial Crew Program in 2010 before the final Space Shuttle flight. It eventually chose Boeing and SpaceX to develop manned spaceflight systems for NASA, but the rigorous testing and design reviews have dragged on for years. Boeing eventually settles on a crew pod called the CST-100 (see above), which is a new design based partially on the old Apollo command modules. Meanwhile, SpaceX developed the Dragon v2 based on its successful unmanned cargo vehicle. SpaceX’s vehicle would feature full reusability.
The GAO report takes into account the current state of testing and design for both crew vehicles. It notes that NASA needs to certify every detail of the spacecraft before it can have astronauts aboard them for a trip to the International Space Station. That does not necessarily mean the vehicles won’t be ready. SpaceX has been talking about sending a paying customer on a trip around the moon, although that mission was delayed earlier this year.
NASA currently pays the Russian space agency for seats aboard Soyuz capsules, which is expensive. The agency has only secured spots on Russian rockets through the end of 2019, and now there might be a nine-month gap between the end of Soyuz service and the first Commercial Crew Program launches.
The GAO says that it’s possible neither launch partner will be certified to carry astronauts before August of 2020. NASA currently has no contingency plans in place if the program can’t get up and running in 2019. The Soyuz is a non-reusable vehicle, so manufacturing and planning for launches is a multi-year process. If NASA wanted more seats, they would not be available before 2021. That doesn’t do any good for the possible commercial crew availability gap.
A best-case scenario would be that Boeing completes certification in December 2019 and SpaceX follows a month later, according to the GAO. If that timeline doesn’t hold, there may be fewer Americans on the ISS for a while.
Top-Secret ‘Zuma’ Satellite Launched by SpaceX May Have Been Lost
The recent "Zuma" launch appeared to go off without a hitch, but now there's reason to think the US spy satellite might have been destroyed before going into operation.
James Webb Space Telescope Completes Deep-Freeze Testing
After removing Webb from the deep freeze, NASA now reports that all systems are go.
SpaceX Falcon Heavy Launch Delayed by US Government Shutdown
After previously suggesting a government shutdown would not delay the Falcon Heavy project, SpaceX now says it won't be able to test the rocket during a government shutdown. Even if the current impasse in Washington is solved, we're not out of the budgetary woods just yet.
SpaceX Test Fires Falcon Heavy Rocket
SpaceX has successfully test fired the Falcon Heavy for the first time ever, proving that if nothing else, the engines will be able to ignite and send the rocket upward. Everything after that is still unknown.
