May 18, 2026 Quick space links

- University to do biology experiment on Dawn Aerospace’s as-yet unflown suborbital spaceplane
Dawn has only flown a smaller prototype at lower altitudes. It remains unclear when actual suborbital spaceflights will take place.
- Axiom Space establishes a wholly owned Japanese subsidiary
The goal is to win Japanese commercial and government contracts for its Axiom commercial space station.
- Chinese pseudo-company Zenk Space aims for June ’26 debut launch of its Zhihang-1 rocket
Detailed write-up, but all remains uncertain. The company claims it raised more money, and eventually hopes to recover the first stage engines for reuse (similar to ULA’s plan for Vulcan).
- On May 17, 1968 the United States launched Europe’s first satellite, Iris, using a Scout-B rocket from Vandenberg
Iris studied the Sun’s output, and confirmed earlier space telescope observations that the aurora was caused by charged particles from the solar wind following the Earth’s magnetic field lines down to the poles.
- On May 17, 1969, a day after Venera- 5, the Soviet Venera 6 operated for 51 minutes as it descended through Venus’s nightside atmosphere
At seven miles altitude its ceased operations due to the pressure from the Venusian atmosphere. Both spacecraft confirmed the hellish atmosphere of Venus, sixty times denser than Earth’s, with temperatures ranging from 750 to 1,000 degrees Fahrenheit.
