What Did The Company That Made The Hubble’s Mirror Not Tell Nasa?

NASA has established how a mirror aboard its $1.5 billion Hubble Telescope came to be the wrong shape. The agency said last week that errors in a test instrument apparently led Perkin-Elmer, which fabricated the optics, to finish the 2.4-metre primary mirror of the Hubble Space Telescope incorrectly.

How Big Was The Flaw In Hubble’s Original Primary Mirror?

Hubble’s main mirror had a major defect, a spherical aberration caused by a manufacturing error. The flaw was just 1/50th the thickness of a sheet of paper. It took three years before NASA could mount a repair mission. On Dec.

Who Controls Hubble Space Telescope?

NASA

How Big Is The Mirror On The Hubble Telescope?

Hubble’s primary mirror is 2.4 meters (7 feet, 10.5 inches) across. It was so finely polished that if you scaled it to be the diameter of the Earth, you would not find a bump more than 6 inches tall. Hubble is 13.3 meters (43.5 feet) long — the length of a large school bus.

Is Hubble Visible From Earth?

Hubble’s low orbit means many targets are visible for slightly more than half of an orbit’s elapsed time, since they are blocked from view by the Earth for almost one-half of each orbit.

When Was Hubble Last Serviced?

Servicing Mission 4 (SM4): May 11-24, 2009 The Hubble Space Telescope was reborn with Servicing Mission 4 (SM4). The fifth and final servicing of the orbiting observatory flew aboard space shuttle Atlantis (STS-125) May 11–24, 2009.

How Far Can Hubble See?

about 10-15 billion light-years

How Long Will Hubble Last?

five years

What Was Wrong With The Hubble?

Shortly after the Hubble Space Telescope’s launch in 1990, operators discovered that the observatory’s primary mirror had an aberration that affected the clarity of the telescope’s early images. The result was a mirror with an aberration one-50th the thickness of a human hair, in the grinding of the mirror.

What Is The Hubble Mirror Made Of?

Instead of a solid core, Hubble’s primary mirror has a honeycomb core, reducing its weight from 8,000 pounds (3,636 kg) to 1,800 pounds (818 kg). Both mirrors are coated with thin layers of aluminum and magnesium fluoride.

How Heavy Is The Hubble Telescope?

The telescope is 43.5 feet (13.2 meters) long, weighs 24,500 pounds (11,110 kilograms) and cost $2.5 billion. Hubble’s six cameras and sensors see visible, infrared and ultraviolet light. At the heart of Hubble is its 8-foot-diameter (2.4 meters) primary mirror.

How Much Did It Cost To Fix The Hubble Telescope?

If detected prior to launch, the repair would have cost $2 million, an investigation into the cause of the flawed mirror found. But with Hubble orbiting 355 miles above Earth, NASA decided to fix it during the planned 1993 servicing mission.

Can I Look Through The Hubble Telescope?

Hubble flies around, or orbits, high above Earth and its atmosphere. So, Hubble can see space better than telescopes on Earth can. Hubble is not the kind of telescope that you look through with your eye.

Can The Hubble Telescope See The Moon?

As you’re well aware, no telescope on Earth can see the leftover descent stages of the Apollo Lunar Modules or anything else Apollo-related. Not even the Hubble Space Telescope can discern evidence of the Apollo landings. The laws of optics define its limits.

What Replaced The Hubble Telescope?

The James Webb Space Telescope (JWST or “Webb”) is a space telescope that is planned to be the successor to the Hubble Space Telescope.

How Was The Hubble Deep Field Image Taken?

The image was assembled from 342 separate exposures taken with the Space Telescope’s Wide Field and Planetary Camera 2 over ten consecutive days between December 18 and 28, 1995. In 2004 a deeper image, known as the Hubble Ultra-Deep Field (HUDF), was constructed from a few months of light exposure.

How Many Photos Has The Hubble Telescope Taken?

The image, dubbed the Hubble Legacy Field, represents 7,500 separate exposures. It contains about 30 times as many galaxies as the previous shots.

How Many Telescopes Are In Space?

NASA’s Great Observatories program constructed four orbiting telescopes — the Hubble Space Telescope, the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space Telescope. Other space telescopes, like the James Webb Space Telescope, are being planned and built.
