NASA restarting suborbital rocket and balloon programs
This part sounds encouraging to me:
He [Alan Stern, associate administrator of NASA's Science Mission Directorate] announced that [they] are re-initiating the planetary suborbital rocket and balloon programs, which are ways to fly experimental hardware to high altitudes, above most of Earth's atmosphere, for testing; this will allow people who want to develop new kinds of hardware to "get their TRLs up." TRL refers to Technology Readiness Level, a measure of how confident we can be that new kinds of hardware will work on a space mission. Alan also measured that these programs will allow young workers (or old workers, he remarked) to get experience that will make them stronger candidates as principal investigators on future missions.For NASA, suborbital rockets mean Black Brants and similar throw-aways. There should be an effort to convince NASA to allow reusable suborbital vehicles now in development by several companies to compete for those science missions where they can satisfy the altitude requirements. (Also, some of the suborbital RLV companies have expendable second stages at the design stage for sending small payloads to higher altitudes, e.g. some UV observation missions need to reach > 1000km.) RLVs would provide both lower cost per flight than current sounding rockets and provide the new capabilities of rapid turnaround and multiple flights in a short period. For example, a transient stellar phenomena that lasts for a few days could perhaps be examined several times with an instrument not available on an orbital system.
Such vehicles would benefit NASA and its science programs while bolstering a promising new industry with an additional market.
