Exploring an Asteroid Without Leaving Earth
This 45 day mission – which begins Feb. 1, 2018 – will help our researchers learn how isolation and close quarters affect individual and group behavior. This study at our Johnson Space Center prepares us for long duration space missions, like a trip to an asteroid or even to Mars.
The Human Research Exploration Analog (HERA) that the crew members will be living in is one compact, science-making house. But unlike in a normal house, these inhabitants won’t go outside for 45 days. Their communication with the rest of planet Earth will also be very limited, and they won’t have any access to internet. So no checking social media, kids!
The only people they will talk with regularly are mission control and each other.
The HERA XVI crew is made up of 2 men and 2 women, selected from the Johnson Space Center Test Subject Screening (TSS) pool. The crew member selection process is based on a number of criteria, including criteria similar to what is used for astronaut selection. The four would-be astronauts are:
Kent Kalogera
Jennifer Yen
Erin Hayward
Gregory Sachs
What will they be doing?
The crew are going on a simulated journey to an asteroid, a 715-day journey that we compress into 45 days. They will fly their simulated exploration vehicle around the asteroid once they arrive, conducting several site surveys before 2 of the crew members will participate in a series of virtual reality spacewalks.
They will also be participating in a suite of research investigations and will also engage in a wide range of operational and science activities, such as growing and analyzing plants and brine shrimp, maintaining and “operating” an important life support system, exercising on a stationary bicycle or using free weights, and sharpening their skills with a robotic arm simulation.
During the whole mission, they will consume food produced by the Johnson Space Center Food Lab – the same food that the astronauts enjoy on the International Space Station – which means that it needs to be rehydrated or warmed in a warming oven.
This simulation means that even when communicating with mission control, there will be a delay on all communications ranging from 1 to 5 minutes each way.
A few other details:
The crew follows a timeline that is similar to one used for the space station crew.
They work 16 hours a day, Monday through Friday. This includes time for daily planning, conferences, meals and exercise.
Mission: February 1, 2018 - March 19, 2018
But beware! While we do all we can to avoid crises during missions, crews need to be able to respond in the event of an emergency. The HERA crew will conduct a couple of emergency scenario simulations, including one that will require them to respond to a decrease in cabin pressure, potentially finding and repairing a leak in their spacecraft.
Throughout the mission, researchers will gather information about living in confinement, teamwork, team cohesion, mood, performance and overall well-being. The crew members will be tracked by numerous devices that each capture different types of data.

Line 6のHelixにもハムノイズの設定がある。
何でわざわざノイズをいれるの？
って、理解不能だった。
そんなにノイズが重要なら、
真空管アンプ使えよって笑ってしまった。
この動画を見て自分が如何に馬鹿か分かった。
加えてLine6のエンジニアに脱帽。
ノイズに関しては他にも、
この説明文も素通りしていたが、
やっと本当の意味が理解できた。
宮甚商店さん凄いは！
他の動画も幾つか見たけど、
ギターやエフェクターなんかにも、
同様な事が言えるんじゃないかな。
見た目や気分が大事ってのには、
とても共感できる。
いや〜BOSSは初心者のエフェクターとか言ってる輩に、
是非とも見てもらいたい動画だ。
きっと本質を理解出来ないだろうが…
What the records show,
The floats of boats,
Desertion
After many of the men were rather involuntarily brought aboard a warship, many also tried to leave immediately. Not only those who were pressed, there were also many who arrived voluntarily and wanted to leave after some time. This was not very easy, of course, as the ships were secured by the marines. But according to Admiral Phillip Patton (1739-1815), 5662 Seamen, 3909 ordinary Seamen and 2737 landsmen deserted in just two years between 1803-1805. Vice- Admiral Horatio Nelson (1758-1805) , on the other hand, estimated that about 42,000 deserted in the years 1793-1802. One unfortunate ship in particular was HMS Alfred, 74 guns. She lost 6% of her crew in just four days.
But if the ships were so well guarded, how could the men disappear? Well, it has to be said that not all men who disappeared deserted. Some of them found themselves dead on land a short time later, either because they had been murdered or because they had fallen from the rigging. But those who really did desert usually did so when the men went out to fetch water, or on other occasions when they were supposed to go ashore. Now and then some of them tried it in the night with one of the boats. Since not many men could swim, swimming attempts were quite rare. In 1811, however, Robert Hay and a companion with air-filled bladders on their backs attempted to swim away from HMS Ceres, a guardship in the Nore. The men who made it, tried their luck in America, but also in France and Spain.
To prevent disruptions, the boats that were left astern overnight in the late 18th century for emergencies, but they were brought back on board and the emergency principle was discontinued around 1800. In harbours it was normal to have a watchboat circling the ship. And as already mentioned, the marines were deployed to provide protection on board.
But as mentioned above, many managed to escape, but not everyone managed to start a new life. Those who were recaptured and could not hide were court-martialled and should have been hanged. But there were also cases where men were punished by flogging round the fleet, usually with 300 lashes or more. Men caught during the attempt or shortly afterwards were punished directly on board by the captain with 12 or more lashes.
