Arecibo Update

Puerto Rico continues to assess the damage and recover from Hurricane Maria. Here’s the latest on the Arecibo radio telescope on the island’s north coast via Nadia Drake — check out her tweets (@nadiamdrake) and her article for National Geographic [http://news.nationalgeographic.com/2017/09/arecibo-radio-telescope-damaged-puerto-rico-hurricane-maria-science/]. Bottom line: people are OK; telescope, not so much.

Here’s what we know so far about the damage done to Arecibo’s iconic @NAICobservatory: https://t.co/MzwiT1CwRN — Nadia Drake (@nadiamdrake) September 22, 2017

NROL-42 Rescheduled for Saturday Night Pacific time (Sunday morning Eastern)

The United Launch Alliance (ULA) will try to launch the National Reconnaissance Office’s NROL-42 spacecraft on Saturday at 10:30 pm ET Pacific Time (1:30 am ET Sunday). The launch was delayed from last night because ULA had to replace a battery on the Atlas V rocket. The weather forecast for Saturday is not bad — 80 percent “go.”

Tianzhou-1 Reenters

China’s robotic Tianzhou-1 space station cargo resupply ship has reentered and burned up in the atmosphere over the Pacific Ocean. Tianzhou-1 performed three automated refueling tests with the unoccupied Tiangong-2 space station as we reported earlier.

Separately, JAXA and NASA reaffirmed their cooperation on several missions. They include the JAXA-led Martian Moons Exploration (MMX) mission that will study the martian moons Phobos and Deimos and return a sample to Earth; the Chromospheric Lyman-Alpha Spectro-Polarimeter experiment (CLASP-2), a follow-on to the 2015 suborbital CLASP solar physics mission; and the new X-ray Astronomy Recovery Mission (XARM), to replace the Hitomi X-ray spectrometry spacecraft that failed prematurely in 2016.

Our Beautiful Home — Earth

To round out the workweek here’s a wonderful time-lapse video of Earth from Africa up across Italy and over the border between Russia and Kazakhstan taken by astronauts aboard the International Space Station.
