¶Vulcan flies but Peregrine falters. ULAâs inaugural Vulcan Centaur launch took off successfully on Monday, delivering Peregrine, the first NASA CLPS landerâalso Astroboticâs first lunar lander, and also also the USâs first lunar lander in 50 years (excluding the 2009 LCROSS impactor)â, into a trans-lunar injection. Unfortunately, Astrobotic has reported a âcriticalâ propellant loss (imagery consistent with this) and initially experienced spacecraft orientation control issues when trying to face the Sun for charging. The lander was targeting the Sinus Viscositatis lava plain outside the Gruithuisen volcanic domes after 17-19 days in transit and up to 39 days in lunar orbit, which is unfortunately now out of the question. Peregrine is the first of what is now 8 CLPS missions (from 4 providers), intended to kick off a new era of routine, commercial lunar exploration. The 2-meter tall Peregrine lander carries 21 payloads from 6 countries, five of which are funded through CLPS, including near-IR and neutron spectrometers, radiation and volatile monitoring sensors, a lunar landing LIDAR, and the requisite retroreflectors for laser ranging (Astrobotic press kit). Included also are multiple small rovers. The next CLPS mission up to bat, Intuitive Machinesâ Nova-C, is scheduled to launch in mid-February, and Astrobotic has its next mission nominally scheduled for November. The Vulcan rocket, however, performed well as ULAâs long-awaited new launch vehicle, originally planned for launch in June 2021. It is 61.6m tall, 5.4m in diameter, and is powered by Blue Originâs BE-4 methalox enginesâwhile not the first methalox to reach orbit, LandSpaceâs Zhuque-2 snagged that title, BE-4 engines are much more powerful. Here are lots of Vulcan technical details. Many more Vulcan launches are coming, with something like 38 launches planned for Amazon Kuiper aloneâULA is planning to eventually launch two per month, a huge ramp from just three launches in 2023. |
