On 24 April, the United Nations Postal Administration (UNPA) issued six new stamps and three souvenir sheets to celebrate human achievements on planet Mars.

Mars has been a source of curiosity for centuries. In a historic year for exploration, three missions reached their destinations on, and around, the “red planet” in 2021.

This stamp series marks those pioneering achievements:

The United Arab Emirates (UAE) mission to Mars launched its Hope Probe which successfully entered Mars’ orbit on 9 February 2021.

  • The CHF 1,10 stamp features Planet Mars taken by UAE Hope Probe

  • The CHF 1,50 stamp features Emirates Mars Mission “Ready to Launch”

The National Aeronautics and Space Administration (NASA) Mars 2020 mission landed on Mars on 18 February 2021.

  • The 58¢ stamp features Proctor Crater of Mars

  • The $1.30 stamp features the Mars 2020 Perseverance Rover

  • The $1.30 souvenir sheet features the Mars 2020 Ingenuity Helicopter

The China Nations Space Administration (CNSA) launched its first Mars mission “Tianwen-1” which landed on Mars on 15 May 2021. 

  • The €0,85 stamp features the pre-selected landing area for Tianwen-1 mission

  • The €1,00 stamp features the Zhurong Rover operating on Mars

  • The €1,80 souvenir sheet features the Zhurong Rover Landing Platform

The stamp issue was designed by Sergio Baradat of UNPA, and the stamp images were supplied by the Emirate Mars Mission team, CNSA, and NASA, with the support of the United Nations Office for Outer Space Affairs (UNOOSA).

The stamps are available online at www.unstamps.org and/or from shops at UN Headquarters in New York, Geneva, and Vienna where the stamps can be used for mailing.
