According to the UPI news agency, senior Nasa officials only realised the flaw in MPL's thrusters a few days before the landing was to take place on 3 December - when it was too late to do anything about it.
In a statement, Sharif El-Gamal, the president of Soho Properties, which owns 51 Park Place, said workers called the city and the police as soon as they discovered the landing gear.
The craft itself may not survive this, but it gives the project's engineers a chance to practise landing a spacecraft remotely on a relatively small target with a gravitational field that varies immensely from one place to another.
The collection at the New York State Museum in Albany has a large piece of landing gear that went through the roof and landed in the basement of a building next to 51 Park Place.
