FAA delays environmental review of SpaceX's Starship yet another month, to May 31

The FAA has repeatedly pushed back the estimated release date of the final report.

We'll have to wait at least another month to see the results of the U.S Federal Aviation Administration's (FAA) environmental review of SpaceX's Starship program.

The FAA has been working for months on that review — officially known as a programmatic environmental assessment (PEA) — which is assessing the environmental impacts of Starbase, the South Texas site where SpaceX has been building and testing its huge Starship vehicle.

The agency published a draft PEA in September and estimated that the final version would be wrapped up by the end of the year. But the FAA has repeatedly delayed the final PEA, generally by a month at a time, citing the need to analyze the public comments submitted in response to the draft report and discuss next steps with other government agencies

Late last month, the FAA told us that it expected to release the final PEA today (April 29) — but that's not going to happen.

"The FAA plans to release the Final PEA on May 31, 2022. The FAA is finalizing the review of the Final PEA, including responding to comments and ensuring consistency with SpaceX's licensing application," FAA officials wrote in an update today.

"The FAA is also completing consultation and confirming mitigations for the proposed SpaceX operations," they added. "All consultations must be complete before the FAA can issue the Final PEA."

Starship consists of a huge first-stage booster called Super Heavy and a 165-foot-tall (50 meters) upper-stage spacecraft known as Starship. SpaceX is developing the system to take people and cargo the moon, Mars and other distant destinations.

The company is gearing up to launch the first-ever Starship orbital test flight, which will lift off from Starbase and send the upper stage on a round-the-world trek that will end with a splashdown off the Hawaiian island of Kauai, if all goes according to plan.

That flight cannot happen with the final PEA still pending as it is, but it's unclear how much the latest delay will affect SpaceX's Starship plans. SpaceX founder and CEO Elon Musk said last month that the company likely wouldn't be ready to launch the orbital flight test until May at the earliest, citing the need to build and integrate the requisite Raptor engines. (Each Starship stack will need 39 Raptors — 33 for Super Heavy and six for the upper-stage spacecraft.)

Agnikul opens India's first rocket engine factory in Chennai

Space tech startup Agnikul Cosmos today inaugurated India's first-ever facility to manufacture 3D-printed rocket engines in Chennai. Named Rocket Factory 1, it was unveiled by Tata Sons chairman N Chandrasekaran and Isro chairman S Somanath in the presence of Pawan Goenka, the chairman of IN-SPACe (Indian National Space Promotion and Authorization Centre). The 10,000-square-foot facility is located at IIT-Madras Research Park. It will have a 400mm x 400mm x 400mm metal 3D-printer from EOS that will enable end-to-end manufacturing of a rocket engine under one roof. The manufacturing facility has a capacity to make two rocket engines per week and thereby one launch vehicle every month, Agnikul co-founder Srinath Ravichandran told TOI. "This s a milestone for us as we go from R&D phase into core manufacturing with the opening of this facility, and begin productionizing the launch vehicle engine making. We have a lot of inbound interest [for launches] from global quarters...

ISRO is silently building Reusable Launch Vehicle

The Indian space agency is literally growing new wings as it gets ready to test a scaled down version of what can easily be described as the `swadeshi Space Shuttle'. The Indian Space Research Organisation (ISRO) calls it the `Reusable Launch Vehicle' or RLV. If all goes to plan very soon it will be seen flying over the Science City in Challakere, Karnataka, where the first landing experiment is being planned. S Somanath, Chairman, ISRO says "We are working silently on reusable rocket technology, with a very low budget, low cost and low investment." In the past USA and Russia have flown full-fledged winged space vehicles. Russia/USSR flew its vehicle called `Buran' only once in 1988 and the program was then shelved. USA made 135 flights of the Space Shuttle and in 2011 it was retired. Since then in a new burst of energy, USA, China and India are the only countries having an active program of re-useable rocket development. If all goes as per plan India's full...

ISRO is getting ready for Gaganyaan Abort Test with Special Test Vehicle

The first abort test using the special test vehicle (TV) part of #Gaganyaan, which was earlier targeted for the last quarter of this calendar year, is now expected only in early 2023. ISRO chairman S Somanath told: “There’s been a lot of progress & at this juncture we're looking at the first test in early 2023. The test vehicle is already at SHAR (spaceport in Sriharikota) and work on the crew module (CM) and crew escape system (CES) is progressing. As reported earlier, the test — TV technology demonstrator-1 (TV-TD1) mission — will demonstrate the descent phase, parachute deployment and recovery, among other things. While there will be more than one TV-TDs, in the first one, the CM will separate from the TV at a height of around 11km (from sea level), attain an altitude of around 15km before falling back to back in the Bay of Bengal. The Sriharikota ground team will track. Once separated or ejected from TV, CM will have a free fall. Essentially, will demonstrate crew e...
