Space Space Hubble's teoscope was visited in five different missions between 1993 and 2009. Here, two spacewalking astronauts work on Hubble during their first service mission, when the telescope mirror was set and new camera.
When it comes to a telescope, issues will vary.
To continue to continue; Going to learn new things about the universe, the scientists always have larger and better photography to monitor the cosmos from Earth and from orbit. Engineers have already begun to develop the technology required to build the next generation of space relayings, but there is one problem: & # 39; These receptions may be too big for entering the space.
Both in terms of size and weight, the technologists and the technologists already have a planned future; make it faster than today's rockets. That is because telescope abilities are largely dependent on the opening, or the diameter of its main mirror. New "megarockets" as a NASA law system may be big enough for NASA's rehabilitation to launch in the 2030s, but if these initiatives need to go – Within the one-dimensional rocket balance, these goals may sacrifice some scientific potential.

Instead of limiting telescope design for a & # 39; Responding within the largest payload ticket payment ticket available – so completing the science level that can return its instruments – NASA scientists are work to find new ways to find those telegopypanes to go to; stretch them out with a piece and gather them in a place, either robotic or with the help of strikers.
"Large telegraphs give you better range solution and better specialized solution, so the more important transcendent should be included," said Nick Siegler, NASA Exoplanet Research Program's key technology when He was at an exhibition at 233rd of the American Roman Society in Seattle in January. That higher density allows for more telegraphics to see the cèilidh world, look deeper and more. see more clearly than ever. It will also be particularly useful for finding and identifying planets around other stars.
"Indeed, it's great and relative, but the challenge is moving forward," Siegler said. "You have large structures that you're trying to return to smaller structures, and the work that is going into that is really great." For example, NASA's Web Web of James Webb (JWST) – now scheduled for launch on the Ariane 5 hard rocket in 2021 – is going to go to # 39; Responding within the rocaid payroll payment. When the telescope is ready for use, more than 200 moving patterns must be carefully taken before the instrument can work to watch the spectrum.
JWST is the largest space telescope, with its 6.5-meter mirror (21.3ft). The Ariane 5 that launches JWST will be the heavy-preserved rocket that is being installed; Usually used to install satellites into the world. However, these rockets were also used to launch internet initiatives as the BepiColombo mission of the European Spanish Association to Mercury launched last October. Although the JWST has not yet been launched, NASA scientists are already working on tips for continuing. (Warner spoiler: they are even more than JWST!)
NASA engineers have already been working on the blueprints for room halls proposed as the Great UV Optic Cycling Survey (LUVOIR) and Telescope Space Origins (OST) to deal with rocket restrictions today. For each of the two telescope, the engineers came up with two different design options: a 15-inch (50-foot) version that could be launched on a NASA spelling system (SLS) system Upcoming and 8-m (26ft) version that can launch on smaller and more powerful heavy rocket rockets today. These smaller versions are NASA support plans if the SLS are not ready in time; the megarocket has already been overwhelmed and costs harassment.
Astronauts vs. robots
Instead of waiting for someone to build a rocket enough enough to support the space telescopic types that scientists hope to launch in the future, a team of NASA researchers a & # 39; explore the ability of an in-space collection. This process would only result in barriers related to rocket size, but could also improve and launch the cost of developing a new telescope development, described the "Telescope Teascop in Spain" "(iSAT).
It's just the first to go to & # 39; confirm how to build a telescope in space. To make a complex telecommunication collapse, NASA must confirm that the process is not only possible, but also in terms of effective cost and is not too dangerous. These features are largely dependent on whether a warranty, a robot or a combination of the two will be compiled, members of the iSAT team explained at the AAS meeting.
A new concept is not to remove astronauts to work on space telescope; The Hubble Space logo NASA, launched in 1990, launched its service with squirrels for five trips between 1993 and 2009. Although the Hubble struggles were not first built, they installed a new machine and repaired big on the theater. Strongers have not visited an area telescope from Hubble's final service mission.
Although the Hubble service centers have retired the Hubble service initiatives since 2011, NASA could put strikes from the Lunar Orbital Platform. This purposeful station would propose a stepstone for the crew to Mars.
But some researchers, such as Siegler, think that leases would be better for building objects in the space. "Astronauts are expensive," he said. "We think we are able to do this completely." A strategic system for the development of a multi-tech telegraph in-space would have to be a strategic weapon at the International Spey Station, he said.
In the summer months, the iSAT team aims to publish the latest outputs of its study on various options for an in-space collection.
