#10YearsAgo today, the GRAIL mission ended as its twin spacecrafts, Ebb and Flow, deorbited to the lunar surface. The mission created a detailed gravitational map of the Moon, providing insight into its structure and composition.

“Hey, this is great! Talk about being a spaceman, this is it!”

Watch as Ron Evans, the #Apollo17 command module pilot performed a deep space EVA to retrieve a film canister on the outside of the spacecraft: https://apolloinrealtime.org/17/?t=257:43:19

50 years ago today, the #Apollo17 crew completed its time at the Moon and performed a Trans-Earth injection (TEI) burn to return home. #Apollo50th

That's teamwork 👨‍🚀 👨‍🚀

Astronauts Walter Schirra (right) and Thomas Stafford shake each other's hand as they arrive aboard the USS Wasp aircraft carrier, after their nearly 26-hour Gemini-VI-A spaceflight #OTD in 1965. It was the 1st recovery to be broadcast live on TV!

Apollo era legends on NASA TV today? Yes please!!

"We send our good morning on our last wakeup day from the Moon.”

Gene Cernan sent greetings from the #Apollo17 crew to everyone back on Earth #OTD in 1972. #Apollo50th

“Without a doubt the most interesting sample returned from the Moon!”

The oldest known unshocked rock retrieved from the Moon, called Troctolite 76535, was collected by #Apollo17 astronaut Harrison Schmitt. It’s at least 4.2 BILLION years old. @NASAMoon

🤝 Gemini VII, meet Gemini VI-A

The first-ever rendezvous of two spacecrafts with astronauts on board happened #OTD in 1965. This photo of the Gemini VII craft was taken by the crew of Gemini VI.

Gene Cernan: “The pictures speak for themselves. We were pretty happy, pretty tired, and pretty dirty. Look at the faces and you can see the sense of satisfaction. And look at how dirty...look at how filthy we are! And hot. I guarantee you that underwear was soaked.” #Apollo50th
#NASAhistory


50 years ago today, Gene Cernan became the last person to stand on the Moon. Before his return to the #Apollo17 lunar module, he said: “We leave as we came and, God willing, as we shall return, with peace and hope for all mankind. Godspeed the crew of Apollo 17.” #Apollo50th

Farewell to the LRV 👋

Near the end of their last EVA, #Apollo17 astronauts Cernan and Schmitt parked the rover with its camera pointed at the LM to record its launch from the Moon. Over 3 days, they had completed 22 hours of EVAs—the most of all the Apollo missions. #Apollo50th
#NASAhistory


As part of the #Apollo17 Lunar Seismic Profiling Experiment, Harrison Schmitt and Gene Cernan pulled the pins on 8 explosive charges (on the right in the 📷) left at 8 sites, activating timers that would allow them to be exploded roughly 90 hours later. #Apollo50th
#NASAhistory


Seismometers were deployed during each of the Apollo missions that reached the lunar surface and for decades have been used to investigate the internal structure of the Moon.

One of the types of moonquakes detected, originating at moderately shallow depths of 20-30 km, can register up to a startling 5.5 on the Richter scale and can last for over 10 minutes!

More about moonquakes: https://go.nasa.gov/3Y0VNOQ
#NASAhistory


Four geophones connected by cables to the central station of the ALSEP were set up to record the seismic waves created by the launch of the LM, the detonation of the explosives, and any moonquakes or meteorite impacts. @NASAMoon
#NASAhistory


“May the spirit of peace in which we came be reflected in the lives of all mankind”

These words, signed by the #Apollo17 astronauts and President Nixon remain on the Moon’s surface affixed to one of the legs of the lunar lander. #Apollo50th
#NASAhistory


#Apollo17 astronaut Harisson Schmitt suffered from “lunar hay fever” in reaction to the lunar dust. Unlike Earth’s dust particles which are rounded, Moon dust is sharp and abrasive, irritating astronaut eyes, nasal passages, and lungs. #Apollo50th @NASAMoon
#NASAhistory


Curious about how Moon dust feels and smells? 🌔 👃

Find out ➡️ https://go.nasa.gov/3XUI5wQ

And check out how dirty Schmitt's suit is in this photo!
#NASAhistory


And there were issues, such as when the right rear fender extension was torn off, kicking up dust as Schmitt and Cernan drove and reducing visibility. The crew had to make a resourceful repair using duct tape and maps.
#NASAhistory


During #Apollo17, the Lunar Rover Vehicle logged the farthest distance from the LM of any Apollo mission, 4.7 miles (~7.5 km).

As a precaution, the LRV had a walk-back limit in the event of an LRV issue; astronauts had to have enough resources to walk back to the lunar module.
#NASAhistory


For our LRV fans, visiting an LRV driven on the Moon is a bit difficult since the 3 LRVs used for Apollo 15, 16, and 17 missions were left on the Moon. But you can find an LRV used for training at @airandspace.

There’s no wind on the Moon, but that doesn’t mean your flag has to droop. #DYK a horizontal rod with a latch makes the flag appear to be flying in the wind? #Apollo50th

Experience the #Apollo17 astronauts planting the flag: https://apolloinrealtime.org/17/?t=118:21:05
#NASAhistory


So is the flag still there? Images of the #Apollo17 landing site from the Lunar Reconnaissance Orbiter Camera show that in 2011 the flag was still standing and casting a shadow! @NASAMoon

As we celebrate the successful completion of the #Artemis 1 mission today, 50 years ago at this very moment, the #Apollo17 lunar module landed on the Moon.

A bag of soup sounds good right now

@NASA_Astronauts have an array of menu items to stay well fed and hydrated on missions. The #Apollo17 menus had around 2500 calories allocated per day for each astronaut.

Check out some of the menu items during our last trip to the Moon.
#NASAhistory


🥓 Bacon Squares
🥪 PB Sandwich
🌭 Frankfurters
🥫 Lobster Bisque

Like anything going to space, weight and containment matter. That's why the #Apollo17 menu included many soups and puddings. Have a favorite? Comment below! #Apollo50th

#DidYouKnow that the #Apollo17 crew weren’t the only living creatures on the mission? Along with their astronaut counterparts, 5 pocket mice were carried into orbit to assess their exposure to particle radiation. 🐭 #Apollo50th

Today we honor John B. McKay on what would have been his 100th birthday! 🎉 McKay was a Navy pilot in World War 2 before becoming an aeronautical engineer and joining the NACA/NASA to fly the X-15 and other research planes! @NASAaero

For those following https://apolloinrealtime.org/17, have you been curious about who the #Apollo17 crew is talking to in Houston? 8 astronauts including the Apollo 17 support and backup crews took the role of CAPCOM. Bob Parker (top left) was CAPCOM for the lunar EVAs. #Apollo50th

2 years after its 1st flyby of Earth, the Galileo spacecraft snapped this pic of our Moon on its 2nd flyby #20YearsAgo today. Galileo used what flight planners called a "VEEGA," a Venus-Earth-Earth gravity assist, to gain momentum for its trip to Jupiter: https://go.nasa.gov/3UCutn1

“The Blue Marble,” one of the most reproduced and influential images in history, was taken #50YearsAgo today by the #Apollo17 crew on their way to the Moon. #Apollo50th #photography

We have liftoff!

#OTD in 1972, #Apollo17 set out for the Moon, carrying with it astronauts Gene Cernan, Jack Schmitt, and Ron Evans. #Apollo50th

The Taurus-Littrow Valley is correct! The #Apollo17 astronauts went to this site to obtain highland samples older than the impact that created the Imbrium Crater and to investigate the possibility of explosive volcanism. They succeeded at both objectives! #Apollo50th

Selecting a landing site on the Moon is more than just pointing at a map. Topography, imaging, and past mission data are just a few things used to determine a landing site.

Let’s meet the #Apollo17 @NASA_Astronauts.👨‍🚀⬇️ #Apollo50th
#NASAhistory


In 1972, #Apollo17 Mission Commander Eugene Cernan had 2 space flights under his belt, Gemini 9 in June 1966 and Apollo 10 in May 1969. Cernan was also a backup crew member of the Gemini 12, Apollo 7, and Apollo 14 missions.

#Apollo17 Command Module Pilot Ronald E. Evans was selected as a member of the 4th group of NASA astronauts in 1966. He was an electrical and aeronautical engineer, and @USNavy aviator before his assignment to the Apollo 17 crew.

Lunar Module Pilot Dr. Harrison (Jack) Schmitt joined NASA as a member of the first group of scientist-astronauts in 1965. Before NASA, Schmitt worked as a geologist at the @USGS Astrogeology Center. He was on the backup crew for Apollo 15 before being selected for #Apollo17.
