The New York Times has kept me busy of late. In the special section commemorating the fiftieth anniversary of the Apollo 11 moon landing, I had two pieces: one on the future of the American astronaut corps, and another on the haunting restoration of the Apollo Mission Control at NASA Johnson Space Center. Another piece I am particularly proud of is the announcement of a mission to Titan, the mysterious moon of Saturn, and the only place in our solar system other than Earth with standing liquid seas.
NASA Announces New Dragonfly Drone Mission to Explore Titan
(The New York Times)
Because of the nature of its atmosphere, Titan is a very Earthlike place. Chemically, it is much like our world’s primordial past. The surface pressure of Titan is one-and-a-half times the surface pressure of Earth, and the same sorts of interactions between air, land and sea take place. Titan thus has familiar geology. Methane on Titan plays the role that water plays here. Its methane cycle is analogous to Earth’s water cycle. It has methane clouds, methane rain and methane lakes and seas on the surface.
“There’s going to be a tremendous change in the fabric of how we see Titan as a world,” said Dr. Ralph Lorenz of Applied Physics Laboratory, the Dragonfly project scientist in an April interview. He predicted that features of Titan will be, “recognizable, but different in flavor from what you see on Earth and Mars.”
That might include the things that wiggle. Complex organic molecules fall from its atmosphere onto the surface of Titan, gather over long periods of time and can be processed further. If cryovolcanoes erupt on Titan’s surface, as data from the Cassini spacecraft suggests, the organic material can mix with liquid water. Sunlight, at the same time, drives the moon’s photochemistry, introducing energy to a system primed for life.
NASA Reopens Apollo Mission Control Room That Once Landed Men on Moon
(The New York Times)
Apollo mission control had been abandoned in 1992, with all operations moved to a modernized mission control center elsewhere in the building. Center employees, friends, family — and anyone, really, who had access to Building 30 — could walk in, take a seat, take a lunch break and take pictures.
While they were there, they might take a button from one of the computer consoles. Or a switch or a dial, anything small — a personal memento from an ancient American achievement. The furniture fabric and carpet underfoot grew threadbare. The room was dark; none of the equipment had power. Wires hung where rotary phones had once sat. The giant overhead screens in front of the room were damaged, and the room smelled of mildew. Yellow duct tape held carpet together in places.
“You knew it wasn’t right — you just knew,” said Sandra Tetley, the historic preservation officer at the Johnson Space Center. “But it was not a priority. We are an organization that’s moving toward the future, so there is not a budget to do things like this.”
The project began in earnest six years ago. The anniversary loomed, and that was the catalyst to fix up mission control, and to do it right. “We wanted to meet a high standard to restore it, and we were able to meet this 50th anniversary,” Ms. Tetley said.
As New Space Race Beckons, Astronauts Face Identity Crisis
(The New York Times)
Christopher Ferguson trains from 8 a.m. to 8 p.m. at NASA’s Johnson Space Center in Houston. A recent day for him was typical: five hours in a launch simulation with the mission operations team. He trained alongside Sunita Williams, herself a two-time space flier and veteran of the space station.
Halfway through the session, the two swapped roles, preparing for situations that might arise on an actual mission. The balance of the day was spent planning timeline management when inserting a crew into a rocket, so that when the hatch closes, all the right things are on the inside, and all the right things are on the outside.
The difference between Mr. Ferguson and Ms. Williams is that Mr. Ferguson does not work for NASA. He works for Boeing and will fly on the first crewed mission of Starliner. Boeing and SpaceX are part of Commercial Crew, a NASA-supported program that has tasked American companies with building spacecraft capable of carrying astronauts to the space station. NASA has relied on Russia’s space program for launching astronauts since the last shuttle returned to Earth in 2011.
