The next anniversary of the Hubble Space Telescope launch is Saturday, April 24, 2027. It will mark 37 years since Hubble began its journey into space.
When Is the 37th Anniversary of the Hubble Launch?
The 37th anniversary falls on April 24, 2027. The date is fixed because Space Shuttle Discovery launched Hubble on April 24, 1990, during NASA’s STS-31 mission.
Hubble was deployed from Discovery’s cargo bay on April 25, 1990. For this reason, some commemorative material may also appear on April 25, but the launch anniversary itself is observed on April 24.
The original mission date is recorded by the NASA STS-31 mission archive, the NASA Hubble history page, and the European Space Agency.
Where Is the Hubble Anniversary Observed?
The anniversary does not have one official venue. Hubble is a joint NASA and ESA project, so the date is mainly marked through online articles, telescope images, videos, educational activities, and posts from space agencies and astronomy institutions.
Local science museums, observatories, schools, astronomy clubs, and planetariums may arrange their own talks or public observing sessions. These activities are independently scheduled and may take place on April 24 or on the nearest weekend.
Is There an Official 2027 Anniversary Program?
As of August 1, 2026, NASA and ESA have not published a dedicated program for Hubble’s 37th launch anniversary. A detailed schedule may not be released far in advance, especially for an anniversary that is not a major five-year or ten-year milestone.
Official Online Coverage
NASA may publish a new Hubble image, mission update, video, social media feature, or archive collection near the anniversary. Earlier milestone years have included dedicated material such as NASA’s Hubble 35th Anniversary page.
Updates are most likely to appear on the NASA Hubble mission page and the ESA Hubble overview page.
Museum and Planetarium Events
Science centers may offer presentations about Hubble’s images, instruments, servicing missions, or discoveries. Each venue sets its own date, capacity, admission rules, and booking process. An event promoted as a Hubble anniversary activity should not be assumed to be an official NASA or ESA event unless the organizer states this clearly.
Tickets and Viewing Information
No ticket is required to follow the anniversary online. NASA and ESA articles, image galleries, and public videos are normally available without an admission charge.
Tickets may be needed for a planetarium show, museum lecture, observatory program, or other local activity. Visitors should check the host venue’s event page before traveling because opening hours and reservation rules vary.
The anniversary does not include a scheduled launch or a public viewing event at Kennedy Space Center. It commemorates the launch that took place there in 1990.
Can Hubble Be Seen from Earth on April 24?
Hubble travels around Earth, but a visible pass on the anniversary is not guaranteed. Visibility depends on the observer’s latitude, the telescope’s orbital path, local weather, darkness, and sunlight reflecting from the spacecraft.
When visible, Hubble appears as a moving point of light rather than a detailed telescope shape. The anniversary date does not make it brighter or easier to see.
Why Are April 24 and April 25 Both Connected to Hubble?
April 24, 1990 was the launch date. Space Shuttle Discovery carried Hubble into orbit as part of STS-31.
April 25, 1990 was the deployment date. The shuttle crew used its robotic arm to lift Hubble from the cargo bay before releasing it into orbit.
A page about the launch anniversary should therefore use April 24. A separate commemoration of Hubble’s deployment would use April 25.
Does the Anniversary Have the Same Date Every Year?
Yes. The Hubble Space Telescope launch anniversary returns every year on April 24. The anniversary number changes by one each year:
- 37th anniversary: April 24, 2027
- 38th anniversary: April 24, 2028
- 39th anniversary: April 24, 2029
- 40th anniversary: April 24, 2030
The next ten-year milestone will be Hubble’s 40th launch anniversary on April 24, 2030.
