NASA first announced plans to send the first woman and next man to the moon by 2024 last year, but a new report says hitting the targeted date is 'unlikely.'

The report, titled '2020 Report on NASA's Top Management and Performance Challenges,' highlights a number of challenges including funding, scheduling, and scope of the Artemis mission.

Some of the major concerns surround key technologies of the mission, such as the production and certification of the Space Launch System rocket and the completion of the Orion crew capsule.

Among technology restraints, NASA's plans have been impacted by the coronavirus – by mid-April, 12 of the agency's 18 major facilities were closed and could not hit necessary timelines.

'We believe the Agency will be hard-pressed to land astronauts on the Moon by the end of 2024,' the report reads.

'At the very least, achieving any date close to this ambitious goal—and reaching Mars in the 2030s—will require strong, consistent, sustained leadership from the President, Congress, and NASA, as well as stable and timely funding.

'For its part, NASA must determine the true long-term costs of its human exploration programs, set realistic schedules, define system requirements and mission planning, form or firm up international partnerships, and leverage commercial space capabilities.'
